Dear Raymond,
I'm sorry, but I can not understand the suggestions that you send me. I
download pulseaudio from the Debian Wheezy official repository of RaspberryPi,
so I do not have the source code of pulseaudio. At the moment I can modify the
startup parameters of the demon from /etc/pulse/daemon.conf or I can change
load modules and parameters from /etc/pulse/system.pa. If I have to download
the source code and compile it by changing some parts, I need you to tell me
and show me all the specifications for how to do it, which version of the code
download, how to compile etc...
Best regards.</pre>
